From 3.10.0 until 3.17.0, the prompt branch in _create_model_version() accepts schemeless relative sources because path validation runs only when a source has a URL scheme, and mlflow.prompt.is_prompt is interpreted by tag presence rather than a true value. A remote caller can store a server-local path as the model version artifact location and use /api/2.0/mlflow/model-versions/get-artifact to read files accessible to the MLflow server process. Default unauthenticated servers require no privileges, while basic-auth deployments are exposed to authenticated users who can create registered models. This issue is fixed in version 3.17.0.","published":"2026-10-27T20:17:14.340","modified":"2026-10-27T20:17:14.340","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/mlflow/mlflow/commit/81730a2ce4ebcd60d5d18f68c96f422ad7e30772","label":"mlflow/mlflow@81730a2"},"references":[{"type":"WEB","url":"https://github.com/mlflow/mlflow/commit/81730a2ce4ebcd60d5d18f68c96f422ad7e30772"},{"type":"WEB","url":"https://github.com/mlflow/mlflow/pull/25870"},{"type":"WEB","url":"https://github.com/mlflow/mlflow/releases/tag/v3.17.0"},{"type":"WEB","url":"https://github.com/mlflow/mlflow/security/advisories/GHSA-m65p-9j7q-6w33"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-27T20:17:14.340"}}
